One hand equals 4 inches. ! foot equals 12 inches so that equals 48 inches plus 7 inches equals 55 inches. 55 inches divided by 4 equals 13h (52 inches) remainded 3 inches; therefore by my reckoning it is 13.3hh
Seriously? That's odd.. on Toto's passport it says 14hh but we think he grew a bit after he was measured and have assumed he's 14.2hh. So I measured him the other day and he was roughly 4ft 7... then again, he was scooting around because he took a disliking to the tape measure so it's probably not very accurate
